Introduction - Samson Audio SX1200 Mode D'emploi

Introduction

We know you don't like reading owners manuals, but you've just purchased one of the finest sound reinforcement
power amplifiers around, and we want to tell you about it! So, before you plug in, we'd like to suggest you take just a
few moments out to scan these pages. We'll make it as painless as possible, we promise—and, who knows, you might
just pick up a tip or two.
The Samson SX Series stereo power amplifiers have been designed to provide robust, clean output with low distor-
tion and wide dynamic range, along with the dependability demanded by the most professional audio engineers and
installers.
Their convenient 2 rack-space design is compact, and yet there's plenty of power available, with 2 x 300 Watts at 8Ω,
2 x 450 Watts at 4Ω for the SX1200, 2 x 400 Watts at 8Ω, 2 x 600 Watts at 4Ω for the SX1800, 2 x 550 Watts at 8Ω, 2 x
750 Watts at 4Ω for the SX2400, 2 x 700 Watts at 8Ω, 2 x 900 Watts at 4Ω for the SX2800 and a massive 2 x 800 Watts at
8Ω, 2 x 1100 Watts at 4Ω for the SX3200. That power rating is over the full frequency spectrum, from 10 Hz to 55 kHz,
which helps give the SX amps their natural and open sound quality.
For mono applications, a Bridge mode links both channels of the amplifiers, thus providing even more power, with
power ratings of 900 watts for the SX1200, 1200 watts for the SX1800, 1500 watts for the SX2400, 1800 watts for the
SX2800 and a massive 2200 watts for the SX3200 into 8 ohms load.
Input connections are made via Combination connectors allowing for both balanced XLR and balanced 1/4" TRS con-
nections. For the outputs, the SX series amplifiers provide standard 5-way binding posts, as well as a Speakon™ con-
nectors. Front-panel controls and displays include a power switch with LED indicator, as well as independent left and
right channel input level controls. To help you set the correct operating levels, the SX amplifiers include front panel
Signal, Peak and Protection LED indicators.
Like all serious power amplifiers, the SX Series internal electronics are based around a serious power-core, with
over-sized toroid al transformers and large extruded heat sinks. To keep the SX amplifiers running cool, their designs
employ twin internal wind tunnels with forced-air cooling via two temperature-sensitive, variable speed fans, which
greatly reduces the chance of thermal and overheating problems. Multi-stage protection for power-up, over-heating,
over-current, short circuit, low output impedance and DC voltage, assures high reliability under the most demanding
situations.
The SX amps are road tough with their all steel chassis, 19-inch rack mount design and convenient carry handles, the
SX amplifiers are ready for a life of travel, or to make home in a nice fixed installation.
Optimized for live sound venues, houses of worship, commercial installations, and for driving small and medium-sized
live PA systems, the SX amplifiers will deliver reliable power from gig-to-gig, venue-to-venue and day-to-night.
In these pages, you'll find a detailed description of the many features of the SX Series power amplifier, as well as a
guided tour through its front and rear panels, step-by-step instructions for its setup and use, and full specifications.
